Visualizing a new column

To address part 1, I plot learning session satisfaction over time, by instructor, by changing the responses “strongly agree, agree, neither agree nor disagree, disagree, and strongly disagree” to corresponding scores of “2, 1, 0, -1, -2”. I then proceed to plot the mean score per session for all instructors, and per instructor in 2 different ways. This can be done with any factor variable, I did it with learning session satisfaction because I thought it was the best overall rating of how a facilitator did. Broadly speaking it seems like people are very satisfied with the learning sessions, although there is a slight dip as of late that can be attributed to the pandemic, which I denoted as starting April 1, when I recall most things going into lockdown.

This first visual does a good job of emphasising when there were sessions that went poorly, as there are very few negative scores overall.

Time Trend

This plot visualizes the trend per instructor over time very well, if I were to model scores over time I would definitely look at a time based structural break before and after the pandemic:

All Scores

This represents the overall trend and makes the slight decrease lately extremely apparent:
